- Volunteers randomly underwent two experimental sessions on different days and separated by 48 to 72 hours. The combined exercise session consisting of 3 laps in a circuit model with two minutes recovery among laps, performing each of the following resistance and aerobic exercises: knee extension, bench press, knee flexion, rowing in the prone, squat, shoulder press and five minutes of up to down in a 15 centimeters high step between 75-85% heart rate maximum and/or 13 in the rate of perceived exertion (RPE) of Borg Scale score of 6 to 20 points21. Resistance exercise loads were implemented using dumbbells to upper body exercises and weights attached on the legs and arms to lower body exercises. Each resistance exercise was performed in 15 repetitions with the estimative of 50% of one repetition maximum test as suggested by Tiggemann et al.22,23 with the utilization of RPE21. One second for the concentric phase and one second for the eccentric phase to resistance exercise were performed with rhythmic control (Metronome Plus®). The control session was conducted under the same conditions of the combined exercise session, with the exception that subjects did not perform exercises.
